Copper Ultrasonic Metal Welding Equipment For Aluminum And Nickel

Ultrasonic Metal Welding Equipment For Aluminum Copper And Nickel Welder

 
Ultrasonic welding of copper, aluminum, and other non-ferrous metals is a mature bonding process, which is widely used in automobile and consumer electronics fields. Due to the rapid development of new energy electric vehicles and the increasing demand for lithium-ion batteries, the application of ultrasonic welding of copper foil and aluminum foil has increased significantly.
The three main stages of ultrasonic metal welding to form molecular bonds are:
1. The relative movement caused shear and plastic deformation -- initial plastic deformation -- on the rough convex features on the connecting surface.
2. Ultrasonic vibration leads to oxidation layer (or contaminants) dispersion and further plastic deformation of the raised features on the connectors. This leads to increased metal-to-metal contact areas and the formation of welding zones, also known as microworlds.
3. Further ultrasonic vibration will cause the contact surface to increase, which will increase the welding area.
 

The decisive advantage of ultrasonic metal welding is "cold" welding, where joints are formed at temperatures well below the metal's melting point. The temperature is only about 1/3-1/2 of the melting point of the metal (the recrystallization temperature during annealing), which is a solid and solid press welding process.

Technical Parameters:

Advantages of the ultrasonic metal welding equipment:

1, Good electrical conductivity after welding, very low or almost zero resistivity.
2, The ultrasonic metal welding machine is close to cold processing, the workpiece is not annealing, no oxidation trace.
3, High fusion strength.
4, Ultrasonic metal welding machine for welding metal surface requirements are low, oxidation or electroplating can be welded.
5, Ultrasonic metal welding machine welding time is short, do not need any flux, gas, solder.
6, The welding process does not need water cooling and gas protection, welding parts do not deformation.

Application:

New energy vehicle industry: The pole lug welding on the lithium battery pack of electric cars is popular now, as well as the welding of wiring harness and wiring harness inside the car, and the welding of wiring harness and terminal.
The medical profession. The most typical application is pin welding on integrated circuits in medical equipment. The process does not require glue or adhesives, just the bonding of the body material. Such as pacemakers used to treat patients and sensors implanted in the body. In addition, ultrasonic welding is widely used in the manufacture of intravenous catheters, blood/gas filters, dialysis machines, valves, and filters.
Electronics and computer industry: Used in chips, motors, capacitors, flash memory, microprocessors, transformers, and other products. The welding process combines thin metal, usually aluminum or copper, with thick material to seamlessly connect wires and circuits. It can effortlessly connect circuits on a circuit board, making it ideal for the smartphone and computer industries.
Space industry: When making engine parts, non-ferrous metal materials such as aluminum are welded to steel. After welding, the components have high drawing strength, precise size, and a beautiful appearance. It can also meet the requirements of sealing performance and impact resistance of closed chamber after welding.
Refrigeration industry: Copper pipes have been used as refrigeration and air-conditioning cooling system components. Because copper was expensive, aluminum tubes were used instead. However, regardless of whether copper or aluminum tubes are used, ultrasound can be used for sheet welding or sealing.
